SPECIFICATION forming part of Letters Patent No. 278,391, dated May 29, 1883.

I Application filed January 9, 1883. (No model.)

others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,.and to the letters and figures of reference marked thereon, which form a part of this specification.

' This invention pertains to improvements in churns, having for. its object to cause the thorough and rapid churning of the cream; and it consists in the combination and arrangement of parts substantially as hereinafter more fully set forth.

In the accompanying drawings, Figure 1 is' a partly sectional and partly side elevation of myimproved churn. Fig. 2 is a vertical crosssection on the line y y ofFig. l; and Fig. 3 is a side elevation of the dasher removed from the cream-receptacle.

In carrying out my invention I construct tahu cream-receptacle A and its affixed under- I neath water tank or reservoir A preferably of tin and oblong in shape, and each with a corrugated bottom, as seen at an, the purpose of which is to prevent kinking of the tin when exposed to the action of cold cream in the receptacle and of the hot water in the tank or reservoir, as has heretofore been caused by the forces of expansion and contraction.

. The drawingoff of the watery particles from the creamafter churningis facilitated by means of the stoppered openingb' at one end of the receptacle A. The receptacle A is suspended in position by means of thebail B,'affixed thereto, and is reciprocated by grasping it at c and moving it with the hand or otherwise applying motion thereto. I attach importance to the lstoppered vent b and stoppered opening din the hot-water tank or reservoir, by means of which the hot'water can be quickly drawn off to prevent overheating the cream,

whichis a great practical advantage.

0 is the dasher, which has two crossing series of blades or bars, (3, made preferably in practice of galvanized iron, the ends of which are riveted or otherwise fastened to plates 0 which plates are fastened to four corner tubes,

7 0 said tubes being passed through and fastened to a cover, 0 The cover 0 has at its apex a handle or bail, c,bywhich the top, with the dasher and its other attachedor adjunctive parts, may be lifted out ofand replaced in the cream-receptacle. The function of the tubes 0 is primarily to conduct air into the cream while being churned and to produce a continuous circulation of air through the cream. The cover 0 has also a flange, f, depending from its edge and fitting against the inner side of a compound flange, g, said latter flange being fastened to OIfOIIllGd with the cream-receptacle body around an opening therein and extended upward therefrom, and y then, lapping upon itself, extended downward into the said receptacle a short distance, as seen in Figs. 1 and 2. This depending flange g prevents the splashing of the cream up between itself and the cover-flange'fiandthence out of the churn body or receptacle. Supported at its side edges upon the concaved bottom of the cream-receptacle is a pan or tray shaped vessel, D, to aid in holding the dasher in place.

I claim and desire to secure by LettersPatent- , L-The combination, with a cream-receptaole, of a dasher composed of two series of said plates are fastened, the lower end of the and for the purdasher being held by a pan or tray, as and for the purpose set forth.

3. The combination of areceptacle, A,having a corrugated bottom and the compound flange g, extending upwardly from the receptacle, and thence lapping upon itself and projecting into the receptacle as, shown, the churn-cover, the dasher consisting of two series of blades attached thereto, and the tubular corner supports open at both ends, as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
